With progress in industrialization, facilities for generating, delivering, and receiving high levels of electric power are in great demand. The scale of electric power equipment is increasing in both size and complexity. This has contributed to the development of our modern, high-tech and information-based society. However, if the generation of electric power is suspended due to unexpected accidents at power facilities or power stations, a range of equipment the operations of which are dependent on electric power can be damaged, causing substantial socioeconomic losses in an industrial society. A great deal of time and money would be expended to repair damaged facilities at a power station, causing enormous economic loss.In order to detect the deterioration processes of power cables, and to prevent the destruction of power cables, the operation status of power cables should be monitored on a regular basis. We have installed equipment at Korea Western Power Co., Ltd., located in Taean, in order to predict and prevent the destruction of power cables. This is an entirely new installation: a set of equipment invented specifically to measure the insulation resistance of power cables. Installation of the equipment does not cause the flow of earth fault current. This ensures accurate measurement of insulation resistance values by the equipment. We have been studying this equipment in order to develop preventive technology that would show the deterioration processes of power cables.

Display industry in Korea has been rapidly developing over 20 years, now taking the top-class leading position in the world. Nevertheless, many previous studies have mainly focused on major panel set makers. To overcome the drawbacks, this study focuses on supplier companies in the upstream of display industry such as materials, components, and equipments sectors. The research method used in this study is an industry value chain perspective combined with architectural innovation approach. Display panel is produced through fabrication process and modular process, each having a different characteristics of process architecture. This research figured out that there are quite a different development characteristics between materials and components suppliers and equipment suppliers. The number and revenue of materials and components suppliers were quite larger than equipments suppliers. However, the former has been growing mainly in the field of modular process, having a very weak position in the field of fabrication process. On the contrary, equipments suppliers have been showing a continuously growing pattern in the field of fabrication process. The R&D expenditures between these two kinds of suppliers showed a similar pattern. The fabrication process of display panel production is characterized as a highly integral architecture characteristics, so as to be a strong barriers to local suppliers, resulting less development of materials and components suppliers in Korea.

Internet of Things technology is rapidly developing due to the recent development of information and communication technology. IoT technology utilizes various sensors to generate unique data from each sensor, enabling diagnosis of system status. However, the equipment management system currently in effect is a post-preservation concept in which administrators must deal with the problem after the problem occurs, which could mean system reliability and availability problems due to system errors, and could result in economic losses due to negative productivity disruptions. Therefore, this study confirmed that edge controller control decision algorithms for more efficient operation of rectifiers in the factory by applying intelligent IoT (AIoT) technology and domain knowledge-based modeling for each sensor data collected based on this, outputting appropriate status messages for each scenario.
